Much better. But still slow. Check out the lightning network, and the link I posted above for an example of how fast lightning network transactions are.
Just checked it, it’s very fast. Will the speed still the same if the network bigger?
Probably. If the network grows, more nodes will be added as the demand increases (because the nodes who open the channels, get paid a small amount of money. Very small, but still something).
You can run your own nodes, and get paid to open your own channels.
